Number of Particles Formula Elements

Variables
Number of Particles
Number of Particles is the number of particles present in a given sample/mixture.
Symbol: Np
Measurement: NAUnit: Unitless
Note: Value should be greater than 0.
Mixture Mass
Mixture mass is the total mass of given mixture.
Symbol: m
Measurement: WeightUnit: kg
Note: Value should be greater than 0.
Density of One Particle
Density of One Particle is defined as the mass of a unit volume of sediment solids. A simple example is that if 1 cm3 of solid material weighs 2.65 g, the particle density is 2.65 g/cm3.
